BacklashMarth
Smash Lord
Ok from my experience with fighting ROB with Marth i have found dancing blade and counter to be my best friend. He has moves that are easy to counter (Nair, Bair, etc.) so throw out an occasionall SH counter here and there if the ROB is bein an agressive pest. For approaching, i have found it best to make it safe for ROB to projectile camp so he wastes his lazer or gyro (mainly the lazer). When he shoots his lazer, dash in and take advantage of the time he has where he cant use it (same goes for the gyro). Dash in and if u see him spot dodge, u can whip out dancing blade and use the down variation at the end to poke him as he loses invicibility frames. Or you can dash into shield and wait for his reaction then act accordingly. Killing rob is the hardest part, giving him damage...not so much.
